hi there!
i have a question that i hope someone may be able to help me with.

i am using the 'paste' function to concatenate to files together.
$ paste A B

output:
A B
C D

However I want to get rid of the space in between - I have tried the following with no luck:

# delete leading whitespace (spaces, tabs) from front of each line
# aligns all text flush left
sed 's/^[ \t]*//'

# delete trailing whitespace (spaces, tabs) from end of each line
sed 's/[ \t]*$//'

# delete BOTH leading and trailing whitespace from each line
sed 's/^[ \t]*//;s/[ \t]*$//'

Has anyone any ideas, please -- it's driving me mad!
thanks,
thegant
